2014-03-13drm/doc: Add function reference documentation for drm_mm.cDaniel Vetter
While at it do a tiny bit of interface cleanup and convert boolean return values to bool. With this patch all exported functions and inline helpers which are part of the drm_mm public interface are documented. Also drop superflous extern function modifiers since most of drm_mm.h doesn't use them - more consistent that way.

2014-03-13drm/doc: Overview documentation for drm_mm.cDaniel Vetter
kerneldoc polish will follow in the next patch. Hopefully documenting the lru scan support a bit better spurs someone to give this a shot in the ttm eviction code. At least in i915 it helped quite a lot with memory thrashing on platforms where eviction was (we've fixed that too meanwhile) fairly expensive.

2014-03-13drm/doc: Add PRIME function referencesDaniel Vetter
For giant hilarity the DocBook reference overview is only generated when in a level 2 section, not in a level 3 section. So we need to move this up a bit as a side-by-side section to the main PRIME documentation. Whatever. To have a complete set of references add the missing kerneldoc for all functions exported to modules with the exception of the file private init/destroy functions - drivers have no business calling those, so let's just drop the EXPORT_SYMBOL instead. Also reflow the function parameters to align correctly and break at 80 chars - my OCD couldn't stand them while writing the kerneldoc ;-) Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2014-02-28drm/radeon: use variable UVD clocksAlex Deucher
Now that Christian fixed the performance problems with the feedback buffer in mesa, we can enable variable UVD clocks. There are multiple UVD power states associated with different types and numbers of streams. This uses the appropriate state based on that information rather than always using the fastest UVD clocks which saves some power. One possible downside is that this may adversely affect decode benchmarks since these power states target specific playback requirements rather than maximum performance. If that becomes an issue, we can add a sysfs attribute to force the max UVD state. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>

into drm-next Updates from Jean-Fracois for the TDA998x driver, which are on top of the fixes you have previously pulled, except these changes aren't intended for -rc, but the next merge window. Several of these are issues of correctness - passing more correct HDMI info packets, not reading registers in older chips documented as write only (despite appearing to be read/write in later chips). Others are code cleanups (using definitions rather than constants where we have them already in the kernel). Additional functionality is also added by way of optional support for the IRQ from the TDA998x, which allows us to avoid busy-waiting for the EDID reads. * 'tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox: drm/i2c: tda998x: always use the same device for all kernel messages drm/i2c: tda998x: adjust the audio clock divider for S/PDIF drm/i2c: tda998x: code optimization drm/i2c: tda998x: remove the unused variable ca_i2s drm/i2c: tda998x: make the audio code more readable drm/i2c: tda998x: use irq for connection status and EDID read drm/i2c: tda998x: always enable EDID read IRQ drm/i2c: tda998x: add DT documentation drm/i2c: tda998x: add DT support drm/i2c: tda998x: don't read write-only registers drm/i2c: tda998x: don't freeze the system at audio startup time drm/i2c: tda998x: change probe message origin drm/i2c: tda998x: code cleanup drm/i2c: tda998x: clean up error chip version checking drm/i2c: tda998x: check more I/O errors drm/i2c: tda998x: simplify the i2c read/write functions drm/i2c: tda998x: use ALSA IEC958 definitions and update audio frequency drm/i2c: tda998x: add the active aspect in HDMI AVI frame drm/i2c: tda998x: use HDMI constants

This fixes bug introduced in 667a6b7a (regulator: max14577: Add missing of_node_put). The DTS parsing function returned number of matched regulators as success status which then was compared against 0 in probe. Result was a probe fail after successful parsing the DTS: max14577-regulator: probe of max14577-regulator failed with error 2 Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Reviwed-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

Pull devicetree fixes from Grant Likely: "Device tree compatible match order bug fix This branch contains a bug fix for the way devicetree code identifies the type of device. Device drivers can contain a list of of_device_ids, but it more than one entry will match, then the device driver may choose the wrong one. Commit 105353145e, "match each node compatible against all given matches first", was queued for v3.14 but ended up causing other bugs. Commit 06b29e76a7 attempted to fix it but it had other bugs. Merely reverting the fix and waiting until v3.15 isn't a good option because there is code in v3.14 that depends on the revised behaviour to boot. This branch should finally fixes the problem correctly. This time instead of just hoping that the patch is correct, this branch also adds new testcases that validate the behaviour. The changes in this branch are larger than I would like for a -rc pull, but moving the test case data out of out of arch/arm so that it could be validated on other architectures was important" * tag 'dt-for-linus' of git://git.secretlab.ca/git/linux: of: Add self test for of_match_node() of: Move testcase FDT data into drivers/of of: reimplement the matching method for __of_match_node() Revert "of: search the best compatible match first in __of_match_node()"

2014-02-21irqchip: orion: Fix getting generic chip pointer.Andrew Lunn
Enabling SPARSE_IRQ shows up a bug in the irq-orion bridge interrupt handler. The bridge interrupt is implemented using a single generic chip. Thus the parameter passed to irq_get_domain_generic_chip() should always be zero.

2014-02-21usb: chipidea: need to mask when writting endptflush and endptprimeMatthieu CASTET
ENDPTFLUSH and ENDPTPRIME registers are set by software and clear by hardware. There is a bit for each endpoint. When we are setting a bit for an endpoint we should make sure we do not touch other endpoint bit. There is a race condition if the hardware clear the bit between the read and the write in hw_write.
